The 4310HSA Sentronic is an electrically controlled closer/holder designed to provide easy passage for groups of pedestrians through high traffic doors. Pedestrians moving through the doorway trigger the built in scanner. When the door is opened to 80 Deg. or more, the door is electrically held open to minimize wear on the door hardware. After the last pedestrian in a group passes through the doorway, the system timer releases the hold open, closing the door. The single lever trach arm closer is designed for pull side mounting.
